Mu gihe cyo kuganira ku dushya n'iterambere mu buryo bw'amashanyarazi bw'imodoka zikoresha amashanyarazi, akenshi bibanda ku bice by'ingenzi nka unit y'ingenzi igenzura n'ibikoresho by'amashanyarazi, mu gihe ibice by'inyongera nka capacitors bikunze kwitabwaho gake. Ariko, ibi bice by'inyongera bigira ingaruka zikomeye ku mikorere rusange ya sisitemu. Iyi nkuru izasuzuma ikoreshwa rya capacitors za filimi za YMIN mu mashini zikoresha amashanyarazi kandi isuzume uburyo bwo guhitamo no gukoresha capacitors mu modoka zikoresha amashanyarazi.

Mu moko atandukanye ya capacitors,capacitors za electrolytic za aluminiyumubafite amateka maremare kandi bafite umwanya ukomeye mu bijyanye n'amashanyarazi. Ariko, bitewe n'iterambere ry'ibikenewe mu ikoranabuhanga, imbogamizi za capacitors za electrolytic zarushijeho kugaragara. Kubera iyo mpamvu, havutse ubundi buryo bwiza bwo gusimbuza—capacitors za filime.

Ugereranyije na capacitors za electrolytic, capacitors za filime zitanga inyungu zikomeye mu bijyanye no kwihanganira voltage, ESR nke, kudahindagurika cyane, kudahindagurika cyane, no kuramba igihe kirekire. Ibi biranga filime bituma capacitors ziba indashyikirwa mu koroshya imiterere ya sisitemu, kongera ubushobozi bwo gukoresha umuyoboro w'amashanyarazi, no gutanga imikorere yizewe mu bihe bikomeye by'ibidukikije.

Imbonerahamwe: Ibyiza byo kugereranya imikorerecapacitors za filimena capacitors za electrolytic za aluminiyumu

Mu kugereranya imikorere ya capacitors za firime n'aho imodoka zikoresha amashanyarazi zikorera, biragaragara ko hari urwego rwo hejuru rw'imikoranire hagati yazo. Bityo, capacitors za firime nta gushidikanya ko ari zo zikundwa cyane mu gikorwa cyo gushyira amashanyarazi ku modoka zikoresha amashanyarazi. Ariko, kugira ngo zikoreshwe neza mu modoka, izi capacitors zigomba kuzuza amahame akomeye y'imodoka, nka AEC-Q200, kandi zigagaragaza imikorere yizewe mu bihe bikomeye. Hashingiwe kuri ibi bisabwa, guhitamo no gukoresha capacitors bigomba gukurikiza aya mahame.

Sisitemu ya OBC (On-Board Charger) ubusanzwe igizwe n'ibice bibiri by'ingenzi: uruziga ruhindura ingufu za AC moteri DC, n'icyuma gihindura ingufu za DC-DC gitanga voltage ikenewe ya DC yo gusharija. Muri iki gikorwa,capacitors za filimeshakisha porogaramu mu bice byinshi by'ingenzi, harimo:

●Gusesengura EMI
●DC-Link
●Gushungura ibyavuye mu bushakashatsi
●Ikigega cy'amazi gihumeka

02 Imiterere y'ikoreshwa rya capacitors za filime muri OBC

YMINitanga ubwoko butandukanye bw'ibikoresho bya capacitor ya filime bikwiriye gukoreshwa muri DC-Link no mu gutunganya umusaruro. Ikigaragara ni uko ibi bikoresho byose bifite icyemezo cya AEC-Q200 cy'urwego rw'imodoka. Byongeye kandi, YMIN itanga moderi zihariye zagenewe ibidukikije birimo ubushyuhe bwinshi n'ubushuhe bwinshi (THB), bigatuma abakora porogaramu barushaho kugira ubworoherane mu guhitamo ibice.

Ibikoresho bya DC-Link Capacitors

Muri sisitemu ya OBC, capacitor ya DC-Link ni ingenzi mu gushyigikira no kuyungurura umuriro hagati ya circuit ya rectifier na converter ya DC-DC. Inshingano yayo y'ibanze ni ukwinjiza umuvuduko mwinshi w'amashanyarazi kuri bisi ya DC-Link, ikarinda umuvuduko mwinshi w'amashanyarazi ku muvuduko wa DC-Link no kurinda umutwaro ku muvuduko ukabije w'amashanyarazi.

Imiterere y’ibikoresho bya capacitor bya filime—nk’ubushobozi bwo kwihanganira amashanyarazi menshi, ubushobozi bunini, no kudakoresha polarite—bituma biba byiza cyane mu gutunganya DC-Link.

YMIN'sMDP (H)urukurikirane ni amahitamo meza kuri capacitors za DC-Link, itanga:

Ibikoresho byo gushungura ibisohoka

Kugira ngo hongerwe imiterere y’ingufu za DC za OBC, hakenewe capacitor ifite ubushobozi bunini kandi ifite ESR nke. YMIN itangaMDPCapacitors za filime za DC-Link zifite voltage nkeya, zifite:

Ibi bicuruzwa bitanga imikorere myiza, kwizerwa, no guhuza n'imikorere y'imodoka zisaba akazi kenshi, bigatuma imikorere ya OBC igenda neza kandi ihamye.
